I didn't use synths often, and when I did there were majors present so Destiny 2's system would have eliminated my need for them. I don't care either way, but I really can't see how it would hurt people who like a challenge. Either way, synths are probably gone for good. Anyway, below are my tips for having fewer ammo problems. Try more ammo efficient weapons. Also switch often, at least before your ammo reserves drop to half capacity. This should help. If I use a bad archetype of any weapon type, I can burn ammo too fast to replenish. It's okay to use one fast burning weapon like Coldheart or SMGs, but having two weapons that consume ammo quickly isn't going to end well. Example: My preferred loadout is Nameless Midnight, Martyr's Make, and Man O' War. Nameless Midnight doesn't have insane reserves, but doesn't run out of ammo all the time. Auto rifles are just crazy for damage, and Martyr's Make has a magazine and ammo capacity to match. Man O' War is a linear fusion. Any fusion can carry adequate ammo. As I said, one ammo-hungry weapon won't kill you. I usually don't use any, though.
